I detected this error, when I programed some kind of stabilizer library
for
programming with Fago, before there was a 256K - compatible debugger.
It was able, to stabilize a program with a lot of errors on a normal
calc, but
hang up on the tiger-emu. I expected the normal stackframe, 8 bytes more
on the stack, than normaly (actually I got out this, just by printing
the
stackpointer-value, then I realized, that I allways had to add #8 onto
a7, to get the exception to return properly (now I know, that this
is normal, and which information are put onto the stack))
